SHUTTLE ATTACHIMENT.

Specification of Letters Patent.

Patented May 4:, 1909.

Application filed September 8, 1908. Serial No. 452,016.

To all whom it may concern:

Be it known that I, EDEN MILTON BAL LANTINE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Shuttle Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in attachments for shuttles and my object is to provide a supporting device for the bobbins employed in connection with the shuttles.

A further object is to provide means for securing the bobbin-supporting device to parts of the shuttle.

A still further object is to provide means for holding the supporting device in a fixed position and a still further object is to provide means in connection with the supporting device whereby bobbins of di'lferent lengths may be securely held in position.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claim.

In the accompanying drawings which are made a part of this application, Figure 1 is a sectional view through a shuttle, showing my improved bobbin-holding device applied to use therein. Fig. 2 is a plan view of the bobbin-holding device removed from the shuttle. Fig. 3 is a detail plan view of the socket employed for securing the bobbin-holding device to the shuttle. Fig. 4c is a longitudinal sectional view through the latch employed for holding the bobbin-supporting device in engagement with the socket and, Fig. 5 is a perspective view of a slightly modified form of latch.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a shuttle, which may be constructed in the usual or any preferred manner and 2 in dicates a recess, in which the usual form of bobbin is adapted to be located. In order to rotatably mount the bobbin within the recess 2, I provide a spindle 3, which is provided with shoulders 4, upon which the bobbin (not shown) is adapted to rest, one end of the spindle 3 having a stop 5 thereon which limits the movement of the bobbin in one direction. The opposite end of the spindle 3 from that containing the stop 5, is adapted to be introduced into a socket 6, one end of which is introduced into a channel 7 formed in the shuttle l and at one end of the recess, said socket being pivotally mounted in the channel by introducing a pin 8 through an eye 9 on the socket 6 and through the adjacent walls of the shuttle and it will be readily seen that by swinging the socket on the pin 8, until the end of the spindle having the stop 5 thereon is clear of the recess 2, said spindle may be readily introduced into or removed from the socket. The spindle is removably secured in the socket 6 by providing a notch 10 in that portion of the spindle 3 entering the socket and forming an opening 11 in-one wall of the socket and in position to be in alinement with the notch 10 when the spindle is introduced into the socket, the opening 11 permitting the tongue 12 of a spring latch 13 to pass into engagement with the notch in the spindle, which tongue, when so engaged, holding the spindle from casual removal from the socket.

The opposite end of the spring latch 13 is secured to the wall of the shuttle 1 in any preferred manner, as by introducing a screw 14 through an opening in the end of the latch and into the body of the shuttle, the latch being so arranged that the body thereof extends over and engages one face of the socket 6 and directs pressure thereon, the tension of the spring holding the socket against casual swinging movement on its pivot pin and to prevent horizontal swinging movement of the socket, the longitudinal edges of the latch 13 may be provided with flanges 15 which extend over and engage the lateral faces of the socket when the socket is in its closed position.

Instead of providing the latch 13 with the flanges 15, that form of latch shown in Fig. 5 may be employed, in which construction the flanges are dispensed with and the ends of the tongue 12 provided with upwardly extending ears 16, which receive the socket and hold the same against lateral displacement.

The bobbins usually are of such lengths as to substantially fill the space between the stop 5 and the end of the recess 2 containing socket.

the channel 7, but should a shorter bobbin be used, a collar or washer 17, as shown by dotted lines in Fig. 1 of the drawings may be inserted around the socket 6 to fill the space between the end of the shuttle and the bobbin.

In removing the s indle from the socket, to supply a new bob in for the shuttle, the end of the spindle containing the stop 5 is swung outwardly, this movement bringing the pivoted end of the socket against the latch 13 and forcing the same outwardly, which will release the tongue 12 from the notch 10 and permit the spindle to leave the A new bobbin is then placed thereon when the socket is again swung outwardly and the end of the spindle introduced into the same its full length, the tension of the latch returning the spindle to the recess when the spindle is released, and entering the tongue 12 into engagement with the notch in the spindle.

It will thus be seen that I have provided a very chea and efiicient means for removably securing a spindle to a shuttle and one wherein the spindle will be held rigid while in the shuttle and it will likewise be seen that I have provided means for quickly re leasing the s indle when it is desired to supply a new iiobbin for the shuttle.

What I claim is:

A device of the character described, com-- prising a shuttle, a socket pivotally hung in said shuttle near one end and having a rectangular chamber, said socket being rectangular for a portion of its length upon the outer side and cylindrical in outline the remaining portion thereof, said rectangular portion having a notch in its under side, a spindle having a rectangular portion received by said socket and provided with a notch in its lower edge registering with the notch in said socket, and a spring latch having one end secured to said shuttle and the other end provided with an upward extension engaging the notch in said spindle and passed through the notch of said socket, said latch also having lateral flanges embracing the rectangular portion of said socket.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
